Wodonga police have been patrolling the area following a large number of complaints about people exceeding the 40km/h limit.

The speed limit has halved while the border checkpoint has been in place.

Sergeant Cameron Roberts said most people were adhering to the changes, but said some "just won't behave".

"They feel that what applies to the vast majority doesn't apply to them," he said.

A short enforcement operation last week nabbed six drivers travelling well above 40km/h.

Half lost their licence.

In Victoria, anyone caught travelling 25km/h over the speed limit is banned from driving for three months, meaning people only need to hit 65km/h to be disqualified.

"We were also applying some reasonable tolerance - it wasn't strict enforcement by any means," Sergeant Roberts said.

"The ones we focused on were the ones who didn't just put their toes over the line, they pole vaulted over it in terms of speed.

"They were travelling well above the limit.

"You see people who want to pass others and chop in in front of them.

"There have been numerous complaints."

The highway patrol member spoke out about the problem in the hopes motorists will slow down.

People can again expect to see police monitoring speed on the causeway.

"The majority of people are doing the right thing and they're quite entitled to see something done with the ones who do the wrong thing," he said.

"They're increasing the risk for everybody.

"We will be back there and we'd prefer everyone just played the game.

"There's obviously a lot of frustration about having to show your permit and getting checked crossing over.

"We completely understand that.

"That aside, we just want people to behave safely on the approach to the checkpoint."

He said the speed reduction helped to prevent traffic from banking up.

Sergeant Roberts said drivers caught during Thursday's operation had been travelling up to about 80km/h with some caught above 70km/h.

Police had focused on the small stretch between the traffic lights and Murray River.

He said speeding in that area was an issue as vehicles could quickly back up with little notice.

"When you get up that quick, you know you're doing it," Sergeant Roberts said of those caught.

"You would be passing other vehicles which is a good visual cue that you're going too fast."

Some drivers have also been seen crossing the centre strip near the third lane.

It remains unclear how long the border closures will remain in place.

Crossing times have blown out to more than an hour following the withdrawal of the army from checkpoints.
